Association of Posterior Tibial Tendon Injury with Spring Ligament Injury, Sinus Tarsi Abnormality, and Plantar Fasciitis on MR Imaging

Abstract

Advanced posterior tibial tendon injury has a high association with spring ligament and sinus tarsi abnormalities on MR imaging. There was a low association between advanced posterior tibial tendon injury and plantar fascia abnormality. Patients with posterior tibial tendon injury often have abnormalities of two or more associated structures.
